Abstract
A number of strains of oxidase-positive moraxellas and of neisserias related to Neisseria catarrhalis were characterized with respect to a number of nutritional and physiological properties and could be assigned to several species or species groups on the basis of their phenotypic traits. This grouping was consistent with that established by Bövre on the basis of transformation frequencies for streptomycin resistance. It is proposed to reserve the generic name Moraxella for the oxidase-positive rodshaped organisms, and a redescription of the genus is offered. Following the recent taxonomic proposals of Bövre and Henriksen, the specific name Moraxella osloensis is applied to the nutritionally unexacting strains that accumulate poly-beta-hydroxybutyrate as carbon reserve. The nutritionally exacting strains are assigned to three distinct groups which can be regarded as separate species or as varieties of M. lacunata. The epithets applicable to these groups appear to be lacunata, nonliquefaciens, and bovis. The "false neisserias" could be assigned to at least three subgroups, one of which constitutes the clearly defined entity, N. catarrhalis, which could be distinguished from N. caviae and N. ovis.This publication has 19 references indexed in Scilit:
